engraved co-acting dies, my invention being designed to be carried out in connection with an ordinary printing press and the operation being consequently far more rapid than is possible in the use of the well known die presses. 1

An important object is the provision of a novel die device designed to be secured upon the platen of an ordinary printing press and engageableby printing blocks located in the chase of the press, the die device including a pair of metal plates between which is inserted the sheet of paper to be stamped, this die device being used in connection with the ordinary gage pins on the platen of the press.

Another object is the provision of a die device including a pair of pivotally connected metal plates, one of "which'isformed with a female die member and .upon the other of which is disposed suitable plastic material which forms the male die when pressure is applied to the female member.

An additional object is the provision of an embossing and printing apparatus which will be simple and inexpensive in construction, easy to use, rapid in action, durable in service, and a general improvement in the art.

Referring more particularly to the drawings,'1 make use of a die device which comprises a lower plate 15whic h .isofrectangular fornr-and which may be of any-suitable size. At one end this plate is formed with areflexly bent flange {-16 which extends only partway across. 'Pivoted upon this plate .15 .is an 'upper plate 1 7 which is of re silient metal and which ,is bent, as shown,

whereby itwill be inclined with respect to v the plate 15, the pivot'pointbeingindicated by-thenumeral -18. The :pivoted end of this.

plate 17 engages beneath :the :flange 16 for the purpose'of holding 'thetwo plates nor- .mally superposed.

The upper plate 17 is provided with a cut-out design 19 of the letter or other character to be stamped.

I also make use of any one ofa lurality of inking blocksQO which are type iiighand which are designed to be used in connection with the ordinary chase A of a printing press, the selected block 20 being placed at the desired location within the chase .-and

being held in position by-the usualprinters furniture B and locking quoins C. .It'will .be observed that anydesired printing face intersecting lines, or a plain type surface. Any other design might be used and the lines might be curved or waved, if preferred, as such variations form no essen tial part of the present invention. 7

in, carrying out my invention 1 glue or otherwise secure the die device onto the platen D of a printing press, the position of this die necessarily corresponding to the position of the printing block 20 located within the chase so that when the press is closed the printing block 20 will engage the upper plate 17 of the die device. My die device of course originally includes only the female die formed by the cut-out portion in the plate 17 and in order to form the male die I dispose a quantity of suitable plastic rapidly hardening material upon the lower plate 15 of the die device and then close up the press which will result in forcing this plastic material into the cut-out portion 19. Surplus material squeezed out must of course be scraped away or wiped ofi be 1 fore drying. Some little time must of course be allowed to effect thorough hardening of the plastic material after the above mentioned treatment and the material, when hard, constitutes the male die which cooperates with the cut-out portion 19. Owing to the fact that the upper plate 17 is pivoted upon the lower plate 15, it will be seen that the upper plate may be readily swung to one side, as shown in Figure 4, to permit the disposition of the plastic material upon the lower plate. After the die device is se cured upon the platen the usual gage pins E are placed in position upon the platen so as to properly guide the paper in exactly the same manner as in ordinary printing.

After the printing block has been locked up in the chase and the chase secured upon the press, and after the die member has been prepared as above described, and secured in place on the platen, in conjunction with the usual gage pins, the rollers of the press are inked in the ordinary manner and the press operated in the usual way, and paper is fed to the press by being placed on the platen against the gage pins and between the plates 15 and 17 of the die device. As the press closes and the printing block 20 engages against the plate 17 of the die device, the paper will naturally be forced into the opening 19' and this will result in embossing. The paper thus forced into this opening will of. course contact with the printing sun face of the block E20 and this will result in irinting the embossed portion so as to produce the effect disclosed in Figure 7. i0 1 In some instances it is desirable to provide a raised panel surroundlng the letter or 1 other design and in order to effect this I provide the underside of the upper plate of the die device with a depressed portion 21 formed by grinding away or cutting away a portion of the material of the plate. When the plastic material is placed upon the lower plate of the die member, as above described, in this instance it would result in forming a male die corresponding to this depressed portion 21 so that when the device is used and the press operated, a raised panel 22 will be produced surrounding the letter or design, as shown in Figure 10. a

From the foregoing description and a study of the drawings it will be apparent that l have thus provided a simple and yet highly eflicient embossing apparatus and process by means of which very creditable work in relief may be produced, the relief portion being printed with any suitable design or being left unprinted if preferred, the construction being such that a raised panel of less height than the design and surrounding the design may also be provided. distinct feature is the ease of production of the male die member owing to the use of the plastic material. The construction and arrangement is such that embossing may be effected very rapidly, in fact as quickly as ordinary printing may be effected, no special apparatus being necessary as my die device and printing blocks are used in conjunction with any ordinary or well known. printing press.

While I have shown and described the pre ferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

What is claimed is:

1. An embossing and printing apparatus including a presser block adapted to be locked within the chase of a printing press, in combination with a die device adapted to be secured upon the platen of the press in conjunction with ordinary gage pins, the presser block having any desired design of printing surface to be inked by the press rollers.

2. An embossing and printing apparatus including a presser block adapted to be locked within the chase of a printing press in combination with a die device adapted to be secured upon the platen of the press in conjunction with ordinary gage pins, said. die device comprising a lower plate, plastic material disposed thereon, and further com prising an upper resilient plate formed with an opening constituting the female die and cooperating with the plastic material to form the male die, the upper plate normally diverging with respect to the lower to permit the positioning of'paper therebetween.

3. In an embossing apparatus, a die device comprising upper and lower resilient normally diverging die plates pivotally con nected near one end, the upper plate being swingable laterally With respect to the lower whereby to be disposed in non-obstructing relation thereto, and means normally holding the plates in superposed relation comprising an upwardly extending overhanging per plate.

In testimony whereof 1 hereto aflix my signature.
